Constructor & Destructor Documentation

casa::ROVisIterator::ROVisIterator ( )

Default constructor - useful only to assign another iterator later.

casa::ROVisIterator::ROVisIterator ( const casacore::MeasurementSet ms,
const casacore::Block< casacore::Int > &  sortColumns,
casacore::Double  timeInterval = 0 
)

Construct from casacore::MS and a casacore::Block of casacore::MS column enums specifying the iteration order, if none are specified, time iteration is implicit.

An optional timeInterval can be given to iterate through chunks of time. The default interval of 0 groups all times together. Every 'chunk' of data contains all data within a certain time interval (in seconds) and with identical values of the other iteration columns (e.g. DATA_DESC_ID and FIELD_ID). Using selectChannel(), a number of groups of channels can be requested. At present the channel group iteration will always occur before the interval iteration.

casa::ROVisIterator::ROVisIterator ( const casacore::MeasurementSet ms,
const casacore::Block< casacore::Int > &  sortColumns,
casacore::Double  timeInterval,
const ROVisibilityIterator::Factory factory 
)
casa::ROVisIterator::ROVisIterator ( const ROVisIterator other)

Copy construct.

This calls the assignment operator.

casa::ROVisIterator::~ROVisIterator ( )

Destructor.

Member Function Documentation

void casa::ROVisIterator::allSelectedSpectralWindows ( casacore::Vector< casacore::Int > &  spws,
casacore::Vector< casacore::Int > &  nvischan 
)

Get selected spws and channel counts.

casacore::Vector<casacore::Int>& casa::ROVisIterator::chanIds ( casacore::Vector< casacore::Int > &  chanids) const

Return channel numbers in selected VisSet spectrum (i.e.

disregarding possible selection on the iterator, but including the selection set when creating the VisSet)

casacore::Vector<casacore::Int>& casa::ROVisIterator::chanIds ( casacore::Vector< casacore::Int > &  chanids,
casacore::Int  spw 
) const
casacore::Vector<casacore::Int>& casa::ROVisIterator::corrIds ( casacore::Vector< casacore::Int > &  corrids) const

Return selected correlation indices.

casacore::Vector<casacore::Int>& casa::ROVisIterator::corrType ( casacore::Vector< casacore::Int > &  corrTypes) const
virtual

Return the correlation type (returns casacore::Stokes enums)

Reimplemented from casa::ROVisibilityIterator.

The following throws an exception, because this isn't the language of channel selection in VisIterator.

Assignment.

Any attached VisBuffers are lost in the assign.

void casa::ROVisIterator::selectChannel ( const casacore::Vector< casacore::Vector< casacore::Slice > > &  chansel)

Set up new chan/corr selection via casacore::Vector<casacore::Slice>

void casa::ROVisIterator::selectCorrelation ( const casacore::Vector< casacore::Vector< casacore::Slice > > &  corrsel)
casacore::Vector<casacore::Matrix<casacore::Int> >& casa::ROVisIterator::setChanAveBounds ( casacore::Float  factor,
casacore::Vector< casacore::Matrix< casacore::Int > > &  bounds 
)

Set up/return channel averaging bounds.
